Effect of sequential porcine reproductive and respiratory syndrome and swine influenza on the growth and performance of finishing pigs

The threat to public health posed by antimicrobial resistance in livestock production means that the pig sector is a particular focus for efforts to reduce antimicrobial use (AMU). This study sought to investigate the risk factors for AMU in Irish pig production. Antimicrobial use data were collected from 52 farrow-to-finish farms. The risk factors investigated were farm characteristics and performance, biosecurity practices, prevalence of pluck lesions at slaughter and serological status for four common respiratory pathogens and vaccination and prophylactic AMU practices. Linear regression models were used for quantitative AMU analysis and risk factors for specific AMU practices were investigated using logistic regression. Farms that milled their own feed had lower total AMU (p < 0.001), whereas higher finisher mortality (p = 0.043) and vaccinating for swine influenza (p < 0.001) increased AMU. Farms with higher prevalence of pericarditis (p = 0.037) and lung abscesses (p = 0.046) used more group treatments. Farms with higher prevalence of liver milk spot lesions (p = 0.018) and farms practising prophylactic AMU in piglets (p = 0.03) had higher numbers of individual treatments. Farms practising prophylactic AMU in piglets (p = 0.002) or sows (p = 0.062) had higher use of cephalosporins and fluoroquinolones. This study identified prophylactic use and respiratory disease as the main drivers for AMU in Irish pig production. These findings highlight areas of farm management where interventions may aid in reducing AMU on Irish pig farms.

Dry Diet

Liquid feeding of growing pigs is believed to increase feed intake and growth performance compared to a dry diet. There is little information on the comparative feed conversion efficiency of pigs on the two forms of diet or the underlying physiological basis for the differences and how liquid diets affect the absorptive mucosa of the small intestine. This study was designed to investigate differences in feed utilisation and mucosal structure in modern genotype pigs offered equal amounts of feed in dry and liquid form. Additionally, the effect of reducing the pH of the liquid diet was considered.

And Performance

Satisfactory levels of performance and improved carcass and meat eating quality in growing pigs fed high levels of sugar beet pulp (SBP) have been recently demonstrated by Kay et al. (1990) and Longland et al. (1991). One of the main advantages from feeding SBP was a reduction in carcass fatness and increased returns from improved grading. The objective of this work was to determine whether these benefits could be sustained to heavier finishing weights and to compare differences in the response to SBP as a source of readily fermentable non-starch polysaccharides (NSP) and to oat feed (OF), a cereal by-product high in insoluble NSP, which is less easily degraded.

And Performance

The general well-being of growing pigs is known to be affected by both the quantity/quality of stockperson input invested and the complexity of their housing environment (Pearce et. al., 1989). However, the nature of the interactions which exist between these two factors is still largely unknown. The aim of this experiment was to investigate the separate and interactive effects of handling and environmental enrichment on the welfare and performance of growing pigs.

Dietary Treatments

Two experiments were conducted to evaluate the effect of fermented whole crop cereal on palatability and performance in finishing pigs. In Exp. 1, a total of 20 finishing pigs ((Landrace ´ Yorkshier) Duroc) were allotted to 4 dietary treatments to check the palatability of the dietary feed. Diet treatments were included a basal diet; FW = basal diets + 1% fermented wheat without inoculum, FWI = basal diets + 1% fermented wheat with inoculum, FB = basal diets + 1% fermented barley without inoculum, FBI = basal diets + 1% fermented barley with inoculum. Throughout the experimental period, pigs fed FWI and FBI diets had significantly higher feed palatability compared with FW, FB diets. In Exp. 2, a total of 20 finishing pigs were allotted to 4 dietary treatments (1 pigs/pen, 5 pigs/treatment). Dietary treatments were same as Exp. 1. In nutrient digestibility, pigs fed FWI had higher dry matter digestibility. The number of Lactobacillus in feces was significantly higher in FWI treatments inoculated with feed microorganisms. Our results indicated that dietary supplementation with fermented wheat and barley with supplementing inoculant had a beneficial effect in finishing pigs.

And Performance

The passion fruit seed is a byproduct of the extraction of the passion fruit pulp and can be used for feeding to pigs. Two experiments were conducted (digestibility and performance) to evaluate the use of the passion fruit seed meal in feed for growing and finishing pigs. A digestibility trial was conducted with growing and finishing pigs, in which the passion fruit seed meal (PSM) replaced the reference diet (0% PSM) in levels of 4, 8, 12 and 16%. Thirty barrows were used with average weight of 36.85±4.19. The PSF showed DE and ME of 3.244 and 3.223 Mcal/kg, respectively. In the performance trial, were used 150 pigs, which 75 in the growing phase and 75 pigs in the finishing, with initial body weight of 30.63±1.49 and final of 60.38±4.75 kg and 60.40±1.50 and 90.02±4.84 kg, respectively. Five diets were used, with four inclusion levels of PSM (4, 8, 12 e 16%) and one control diet (0% of PSM). The PSM levels did not influence (P>0.05) the performance variables. In the growing pigs, serum levels of cholesterol increased linearly with (P<0.05) inclusion levels of PSM. Quantitative of carcass traits and meat quality were not affected (P>0.05) by increasing levels of PSM in the diets. We conclude that the PSM can be used up to 16% in growing and finishing pigs diets.

Large Groups

In the U.K., an increasing number of farmers are housing growing-finishing pigs in large straw-bedded courts. While this method of housing is cost effective and has positive welfare perceptions there may be increased competition for the basic necessities such as food and water. This study was conducted to determine the effect of drinking trough space allowance on a number of performance and behavioural parameters when pigs are housed in large groups on straw.
